Expansion joint systems are innovative applications used in pipes and pipelines that are often used in the oil, petrochemical and paper industries, amongst many others. There is a great range in the diversity of expansion joints as they can come in a wide range of sizes and variations. They are generally manufactured in standard dimensions that can reach from 1 to 200 inches in diameter and have the ability to withstand temperatures from minus 300 degrees (°F) up to 4000 degrees (°F), as well as being able to resist at full vacuum or 2000 psig. Expansion joints can be manufactured from a range of different materials such as Stainless Steel, PTFE and Rubber, so there is a product supply available for almost every application.
Engineers were fazed with problems regarding thermal expansions, corrosive and abrasive factors that took effect on the functionality of various applications. Fabric joints can be used in different applications for turbines and pipelines, as they can become prone to challenges including resistance, heat and other factors which can be helped to a great extent with the use of fabric joints. Other applications such as turbines with different membranes and designs, extension joints can be the perfect solution.
Metal bellows are generally used in pipeline systems to help connect pumps and vessels, as the designs I the folds in metal allow grater axial, lateral and angular movement. Ties, pivots and other trimmings can be added to a metal bellow, helping to create a strong, robust and durable design.
Metal expansion joints are crucial components for pipeline technology that are used to counterbalance length changes that generally occur in pipelines from temperature changes. They are also capable of absorbing vibrations developed by pumps, engines, compressors or turbines. This is considered as a cost effective choice to help enhance the life span of a pipeline system, reducing sealing problems and large space required for alternative expansion equipment.
Fluid catalytic cracking units are used within expansion joints to help the expansion joint withstand extremely high levels of heat, pressures and extreme environments/conditions to ensure good functionality.
